PEXALGAS™ GAS PIPING SYSTEMCertified to:• International Fuel Gas Code (IFGC) 2021, 2018, 2015, 2012 & 2009• International Residential Code (IRC) 2018, 2015, 2012, & 2009• Uniform Plumbing Code (UPC) 2021, 2018, 2015, 2012 & 2009• ICC-ES PMG-1588

Meets:• ASTM F1281-2017 – Standard Specification for Cross-linked Polyethylene/Aluminum/Cross-linked Polyethylene (PEX-AL-PEX) Pressure Pipe• AS 4176.8-2010 Multilayer pipes for pressure applications, Part 8: Multilayer pipe systems for consumer gas installations with a maximum operating pressure up to and including 5 bar (500 kPa) - Specifications for systems (ISO 17484-1:2006, MOD)

FeaturesThe characteristics of the PEXALGAS™ pipes make this product highly reliable and extremely easy to install.

Durability and mechanical strength The mechanical characteristics of the PEXALGAS™ pipes are such that the bursting pressure at room temperature (in relation to the pipe diameter) is more than 100 bar.

Smoothness and resistance to scale formationThe extreme smoothness of the inner surface (roughness of 0.007 mm) prevents the formation of deposits such as limescale and also ensures low pressure drops over time.

Resistance to abrasion Crosslinked polyethylene is abrasion resistant since the pipes are not affected by the abrasive action of impurities that are carried.

Flexibility and shape stabilityThe combination of crosslinked polyethylene and aluminum offers excellent flexibility features in bending. The PEXALGAS™ pipe can be bent manually up to the 32 mm (1” eq. ) diameter, with curvature radii of up to 2.5 times the diameter. The excellence of the PEXALGAS™ pipes resides also in its extraordinary shape stability: once bent andinstalled, it maintains the configuration over time allowing a reduction of the number of anchoring clips needed, which in surface mounting is reduced by 40% of the clips required for plastic pipes such as PEX, PE-RT, PP-R, PB, PVC.

EQ. = closest US equivalent fitting size


PEXALGAS™ GAS PIPING SYSTEMThermal expansionThermal expansion is about 8 times lower than that of plastic pipes and is comparable to that of metal pipes. A 10 m PEXALGAS™ pipe subjected to a 50°C temperature difference will expand by 13 mm in contrast to a plastic pipe (crosslinked polyethylene) that expands by 90 mm (3.54”).

LightweightThe pipes are extremely lightweight compared to metal pipes: the weight is 1/3 compared to that of a corresponding copper pipe, 1/10 compared to that of a corresponding steel pipe and 1/2 compared of a corresponding normal CSST pipes.

Acoustic insulationCrosslinked polyethylene is elastic and absorbs vibrations and therefore offers excellent acoustic insulation.

Oxygen and light barrier The butt-welded aluminum layer represents a permanent oxygen and light barrier, avoiding in this way the two main causes of algae formation and corrosion in plastic pipes.

EcologyPEXALGAS™ is manufactured with fully recyclable materials, the production processes are energetically efficient in order to have a low impact on the environment. The manufacturing process adopts “Green Building” sustainability principles, with an eye on environmental protection and conservation of resources.

Jones Stephens sizing tables reflect the real pressure drop of the pipe and fittings. Sizing must be done in accordance with NFPA 54 (National Fuel Gas Code), using both the TUBES and the FITTINGS sizing tables: this means that the results will be perfectly sized for the real installation. Please reference the editable sizing charts to calculate for specific applications.
